Since the long-awaited detection of the Higgs Boson in 2012, particle physicists have been probing deeper into the subatomic realm in the hope of investigating beyond the Standard Model of Particle Physics. In so doing, they hope to confirm the existence of previously unknown particles and the existence of exotic physics, as well as learning more about how the Universe began.
At the Fermi National Accelerator Laboratory (aka. Fermilab), researchers have been conducting the Muon g-2 experiment, which recently announced the results of their first run. Thanks to the unprecedented precision of their instruments, the Fermilab team found that muons in their experiment did not behave in a way that is consistent with the Standard Model, resolving a discrepancy that has existed for decades.

When NASA sends astronauts back to the Moon as part of the Artemis Program, they will be taking the long view. Rather than being another “footprints and flags” program, the goal is to create a lasting infrastructure that will ensure a “sustained program of lunar exploration.” A major element in this plan is the Lunar Gateway, an orbital habitat that astronauts will use to venture to and from the surface.
The first step in establishing the Gateway is the deployment of two critical modules – the Habitation and Logistics Outpost (HALO) and the Power and Propulsion Element (PPE). According to a recent update, NASA (along with Maxar Technologies and Busek Co.) recently completed a hot-fire test of the PPE propulsion subsystem – the first of many that will ensure that the PPE and HALO will be ready for launch by 2024.

Space exploration sure is hard, huh? Luckily, it’s an iterative process, where engineers test and test and test again to work out all the bugs in advance. At least, that’s what we remind ourselves when the prototype goes “kaboom!” Earlier today, the SN11 joins its predecessors by being the fourth Starship prototype to conduct a successful flight test and then explode while attempting to make a landing (or shortly thereafter).

They say, “third time’s the charm.” This was largely the case today as SpaceX made their third attempt at a high altitude flight test at their launch facility in Boca Chica, Texas. Like the previous two attempts, this flight saw a Starship prototype (SN10) with three Raptor engines fly to an altitude of 10 km (6.2 mi), conduct a “belly-flop” descent maneuver, and then return to the launch facility.
As with the previous high-altitude tests, the SN10 successfully launched, reached its apogee, and validated the control fins and aerodynamic surfaces. But unlike the previous tests, the SN10 was able to slow down enough and keep itself upright so it could make a soft landing. While the prototype exploded a few minutes after landing (apparently from a methane leak) the flight was a complete success!

In the coming generations, humanity’s presence in space is expected to grow considerably. With everything from space tourism, the commercialization of Low Earth Orbit (LEO), asteroid mining, and maybe even settlements on the Moon and Mars in mind, there appears to be no limit to what we hope to accomplish. Another interesting thing about the modern space age is the way it is becoming more open and accessible, with more people and nations able to take part.
Unlike the Space Race, where two nations dominated the playing field and astronauts corps were almost exclusively made up of white men, space exploration today is more representative. However, there are still many challenges and barriers for women and people of color in space exploration and the related STEAM fields, not all of which are visible. Addressing these requires that we become better at listening to those who deal with them.
To this end, the Space Court Foundation (SCF) is launching a new series titled “Women of Color in Space.” As part of their mission to foster a conversation about space law and the future of space exploration today, this series interviews women of color who have made it their mission to advance space exploration and fulfill the promise of making space “the province of all of humanity.”

On July 19th, 2020, the Emirates Mars Mission (EMM) – aka. Al Amal (“Hope” in Arabic) – launched from the Tanegashima Space Center in Japan on its way to Mars. This mission, the first interplanetary effort to be mounted by an Arab nation, is being carried out by the Mohammed bin Rashid Space Centre (MBRSC) in the United Arab Emirates (UAE) in collaboration with a number of research institutions internationally.

Another day, another round of testing (and yes, another explosion). Today, on Tuesday, Feb. 2nd, 2021, flight teams at SpaceX’s launch facility near Boca Chica, Texas, conducted a high-altitude test flight with a Starship prototype. Similar to the previous test in December, the SN9 was powered by three Raptor engines, flew to an altitude of 10 km (6.2 mi), then attempted another “belly flop” to test out its fins and aerodynamic surfaces.
As always, the event was broadcast via live stream by SpaceX, NASASpaceFlight, LabPadre, and several other observers. Like the SN8 test flight, SpaceX’s coverage provided multiple vantage points (landing pad, engine compartment, fuselage, aerial drone, etc.) The flight commenced at 2:25:15 P.M. CST (04:25:15 EST; 12:25:15 PST) when the Starship ignited its three engines and began its ascent.

On Sunday, January 17th, Virgin Orbit conducted the second launch test of its LauncherOne rocket, which the company will use to deploy small satellites to orbit in the coming years. The mission (Launch Demo 2) went smoothly and validated the company’s delivery system, which consists of the rocket air launching from a repurposed 747-400 (named Cosmic Girl).
It also involved the successful deployment of 10 CubeSats which were selected by NASA’s Launch Services Program (LSP) as part of the agency’s CubeSat Launch Initiative (CSLI). The event began when Cosmic Girl took off from the Mojave Air and Space Port at approximately 10:50 A.M. PST (01:50 P.M. EST) and flew to a location about 80 km (50 mi) south of the Channel Islands in the Pacific Ocean.

Today, at close to 04:30 PM local time (CST), NASA achieved a major milestone with the development of the Space Launch System (SLS) – the heavy launch system they will use to send astronauts back to the Moon and crewed missions to Mars. As part of a Green Run Hot Fire Test, all four RS-25 engines on the SLS Core Stage were fired at once as part of the first top-to-bottom integrated test of the stage’s systems.
This test is the last hurdle in an eight-step validation process before the Core Stage can be mated with its Solid Rocket Boosters (SRBs) and sent on its maiden voyage around the Moon (Artemis I) – which is currently scheduled to happen sometime in November of 2021.

If human beings intend to become an interplanetary species (or interstellar, for that matter), then we are going to need new propulsion methods that combine a significant level of thrust with fuel-efficiency. One option that NASA has been exploring for decades is spacecraft that rely on nuclear power, which can take the form of nuclear-electric or nuclear-thermal propulsion (NEP/NTP).
In the current era of space exploration, other space agencies are looking into this technology as well. For instance, the UK Space Agency recently signed a contract with the British automotive engineering firm Rolls-Royce. As per their duties, Rolls-Royce will investigate applications for nuclear power and propulsion. Given the company’s record of mechanical, electrical, and nuclear power solutions
